Supertraining

There is nothing misused by the formula I posted. 220-age is the maximum hear 
rate that most people can achieve without significant cardiac events. Without 
knowing anything else about his clients medical history, it's the best formula 
to use as a predictor of cardiac output. Most individuals do NOT have a MHR 
significantly higher than that formula, and I'd challenge to provide eveidence 
to the contrary. MHR will vary between people, and athletes who have trained in 
aerobic training extensively over many years will not see a significant 
decrease in MHR over time and will often maintain the same peak MHR throughout 
their training life ( a MHR similar to a young adult male). But the segment of 
the population that trains regularly and intensly for long periods of time is a 
small portion of the population. For the vast majority of the population, the 
220-age is a good guideline.

Unfortunately the formula cited by Mr. Garrison has been misused by trainers 
for years. The formula was devised by two cardiologists who had done studies 
with regards to stress tests on a treadmill back in the 60s. They were on their 
way to a conference to present their findings and wanted to be able to tell the 
audience what the target max heart rate should be when testing cardiac patients 
on a stress test. They came up with the formula which is often cited by 
trainers and misused. Most individuals have a maximum HR which is much higher 
than what you will find using that formula.Maximum heart rate will vary between 
individuals irrespective of age. Two individuals the same age will most likely 
have different maximum HR.It will also vary depending on the type of activity 
being performed. The more muscle mass being used for a given activity will 
yield a higher maximum HR in the same individualMost people rarely achieve 
their maximum hr in training since the effort is generally very difficult. 
There are devised step tests for various activities designed to help an 
individual reach their max. Perhaps the best way is in competition when a 
person is not thinking about how they feel but are near the finish line. At 55 
my maximum observed HR was 188 and was observed while using a HRM at the end of 
a hard bicycle race. My maximum at age 64 was 175 and was observed also during 
competitive rowing at the end of a 2 K TT. Ralph Giarnella MD Southington Ct
